RENICE(8) BSD System Manager's Manual RENICE(8)
NAME
renice -- alter priority of running processes
SYNOPSIS
renice [priority | [-n increment]] [[-p] pid ...] [[-g] pgrp ...] [[-u] user ...]
DESCRIPTION
The renice utility alters the scheduling priority of one or more running processes. The following who parameters are interpreted as process
ID's, process group ID's, user ID's or user names. The renice'ing of a process group causes all processes in the process group to have their
scheduling priority altered. The renice'ing of a user causes all processes owned by the user to have their scheduling priority altered. By
default, the processes to be affected are specified by their process ID's.
The following options are available:
-g Force who parameters to be interpreted as process group ID's.
-n Instead of changing the specified processes to the given priority, interpret the following argument as an increment to be applied to
the current priority of each process.
-u Force the who parameters to be interpreted as user names or user ID's.
-p Reset the who interpretation to be (the default) process ID's.
For example,
renice +1 987 -u daemon root -p 32
would change the priority of process ID's 987 and 32, and all processes owned by users daemon and root.
Users other than the super-user may only alter the priority of processes they own, and can only monotonically increase their ``nice value''
within the range 0 to PRIO_MAX (20). (This prevents overriding administrative fiats.) The super-user may alter the priority of any process
and set the priority to any value in the range PRIO_MIN (-20) to PRIO_MAX. Useful priorities are: 20 (the affected processes will run only
when nothing else in the system wants to), 0 (the ``base'' scheduling priority), anything negative (to make things go very fast).
FILES
/etc/passwd to map user names to user ID's
SEE ALSO
nice(1), rtprio(1), getpriority(2), setpriority(2)
STANDARDS
The renice utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
The renice utility appeared in 4.0BSD.
BUGS
Non super-users cannot increase scheduling priorities of their own processes, even if they were the ones that decreased the priorities in the
first place.
